Ed Norton, Courtney Love

We have no idea how he put up with her kooky behavior, but Ed Norton did indeed date rocker Courtney Love in the late '90s after the two co-starred in the biopic "The People vs. Larry Flynt" together. The singer -- and widow of Nirvana singer Kurt Cobain -- has called Norton her most stable partner. "He's been more of a daddy to Frances than Kurt ever was," she told Pop magazine in 2006 of Norton's relationship with her daughter.
